5 0

Answer:

  • 50x⁴ - 20x² + 1 = 0

1. <u>Quadratic form</u>

  • 50(x²)² - 20x² + 1 = 0

2. <u>U is</u>

  • x² = u

3. <u>U- substitution</u>

  • 50u² - 20u + 1 = 0

4. <u>Find the discriminant and identify roots</u>

  • d = (-20)² - 4*1*50 = 200
  • u = (20 ± √200)/100
  • u = (2 ± √2)/10

<u>Solve for x</u>

  • x² = (2 ± √2)/10
  • x = ± √((2 ± √2)/10), four roots

If f(x) = 3x^2 +1 and g(x) = 1-x, what is the value of (f-g)(2)
aleksley [76]

Answer:

14

Step-by-step explanation:

Let's find (f-g)(x)

3x^{2} + 1 - (1-x)\\3x^{2} + 1 -1 + x\\3x^{2} + x

Now let's plug in x=2, so to find (f-g)(2)

3(2)^{2} + 2\\12 + 2 = 14

Describe the graph of a quadratic function
maw [93]
So, given a quadratic function, y = ax2<span> + bx + c, when "a" is positive, the </span>parabola<span> opens upward and the vertex is the </span>minimum<span> value. On the other hand, if "a" is negative, the graph opens </span>downward<span> and the vertex is the </span>maximum<span> value. To put it in complicated terms. Or when A is positive the graph is shaped like a U but if A is negative the graph is an upside down U
